Abstract

Program of observations of settlement and pore water pressures was undertaken in a soft organic silty clay for control of construction of a section of the christina river interchange of delaware interstate routes i-95, i-495, and i-295 near wilmington, delaware. The roadway embankment was stabilized by use of vertical sand drains plus surcharge. Values of compression index and coefficient of consolidation computed from field observations were compared with laboratory test data. Undisturbed samples obtained at a later time when primary consolidation was largely complete were utilized to evaluate the gain in the strength of the organic clay stratum. Conditions disclosed by field observations agreed reasonably well with those assumed for design. /author/.
